"Cannot run program 'C:/Program Files (x86)/Java/jdk1.8.0_45/bin/java'": Resolving Intellij IDEA 14.1.4 Java Execution Errors
Problem:
You're trying to run a Java program in IntelliJ IDEA 14.1.4, but you encounter the error message "Cannot run program 'C:/Program Files (x86)/Java/jdk1.8.0_45/bin/java'". This error indicates that IntelliJ IDEA cannot find or execute the Java runtime environment (JRE).
Scenario:
You have a Java project set up in IntelliJ IDEA 14.1.4. You have a JDK (Java Development Kit) installed on your computer, in this case, JDK 1.8.0_45. When you attempt to run your program, you receive the error message mentioned above.
Original Code (Example):
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello, World!");
}
}
Analysis:
This error usually stems from incorrect configuration of the JDK path within IntelliJ IDEA. Here are the most likely causes:
- Incorrect JDK path: The path specified in IntelliJ IDEA does not point to the actual location of the Java executable.
- Missing or corrupted JDK installation: The JDK may not be installed correctly or has been corrupted, leading to missing files.
- Incorrect environment variables: The JAVA_HOME environment variable may not be set correctly or is pointing to an incorrect location.
Solution:
-
Verify JDK Path:
- Navigate to "File -> Project Structure" in IntelliJ IDEA.
- Select "Project Settings -> Project" in the left-hand pane.
- Under "Project SDK," ensure that the correct JDK is selected. If it's not, click on the "New" button and select the directory containing your JDK installation (e.g., "C:/Program Files (x86)/Java/jdk1.8.0_45").
- Click "OK" to apply the changes.
-
Check Environment Variables:
- Open the "System Properties" dialog box (Windows: "Control Panel -> System and Security -> System" or "This PC -> Properties").
- Click on "Advanced system settings" in the left-hand pane.
- Navigate to the "Advanced" tab and click on "Environment Variables."
- Under "System variables," check if "JAVA_HOME" is set. If it is, ensure it points to the correct JDK installation directory (e.g., "C:/Program Files (x86)/Java/jdk1.8.0_45"). If it's not set, click "New," enter "JAVA_HOME" as the variable name, and the JDK installation directory as the variable value.
- Click "OK" to save the changes.
-
Re-install JDK:
- If the above steps don't resolve the issue, you might need to re-install the JDK.
- Download the latest version of the JDK from Oracle's website.
- Uninstall any existing JDK installations.
- Install the new JDK, ensuring you follow the installation instructions carefully.
Additional Value:
- IntelliJ IDEA provides a user-friendly interface for configuring the JDK path. This simplifies the process compared to manually setting environment variables in older IDEs.
- Regularly updating your JDK is recommended for security and performance reasons. This ensures you're utilizing the latest features and bug fixes.

Conclusion:
By ensuring that IntelliJ IDEA correctly identifies and uses the JDK, you can overcome the "Cannot run program 'C:/Program Files (x86)/Java/jdk1.8.0_45/bin/java'" error and successfully execute your Java programs. Regularly checking and updating the JDK path within IntelliJ IDEA is crucial for smooth and efficient development workflows.
